SMoG has made two big new data sets available on the Swedish National Data service (SND) portal under a Creative Commons licence (CC BY-NC-SA 4.0).
One is the GIS-based Time Model of Gothenburg from 1960 to 2015, in 5 year intervals, including the street network, buildings and plots layers. More details here: https://snd.gu.se/en/catalogue/study/snd1154
The other are the Street networks of Stockholm, Gothenburg and Eskilstuna produced as part of the Spatial Morphology Lab (SMoL), including the non-motorised network and the motorised network. More details here: https://snd.gu.se/en/catalogue/study/snd1153
Both data sets are available from the SND upon request.
